COMPACT DRIVE RANGE
September 1st 2003 WEG claims its new CFW-08 range of compact drives is proof-positive that users do not have to compromise on drive size, performance, ease of use or price.
Catering for single phase applications from 0.18 to 3.7kW, and three phase applications from 0.25 to 7.5kW, the range integrates the latest Digital Signal Processor (DSP) and 16bit Space Vector Modulation for optimised motor control and quiet operation.
The CFW-08 operates in two control modes V/F and Sensorless Vector. Features include S acceleration and deceleration ramps, local remote control, dc braking, torque boost, motor slip compensation, JOG, ride through, multispeed (up to eight speeds), maximum and minimum adjustable speeds, two skip frequencies, and flying start.
The V/F is suited to variable torque loads and includes a selectable energy saving feature that reduces motor losses when operating at lower speeds. This control mode also permits the drives to operate in multi-motor applications where more than one motor is supplied by a drive.
Sensorless Vector Control allows the drive to precisely control the speed and torque of a motor, enabling the CFW-08 to be used for demanding duties, such as extruders, conveyors, rewinders and so on. More articles from WEG Electric Motors (UK) Ltd: |
